Application filed April 14, 1921.

T of /iom it may ronwera.

lie it known that We, HLLYAM E. \Vnsou and llicnnr (i. .lA'KKEN. r'itixens ol' the l'nite l States. residing at irlasnu Pity. lowzn and Minneapolis. Minnesota, have invented eertaiu new Illlll useful improvements in Tile. of which the tollowingi is n speeiliezi,

tion.

This invention relates to a tile and more 0 pzutieularly to a tile designed for the surt'aire of tunnel-kiln ears. Aiming the objects ol' this invention are: to ei'instrnrt a tile pnrtienlarly adapted for the pussage of heat and air therethrough: to construct in tile purtienlarly uset'ul tor the hulking of the load hearing surface of a tunnel-kiln mu: to roustruet a tile espeeially adapted for the purpose stated and \\'l)l(li is stiil strong enough to sustain such loads as it may he desirahle to place thereon: to provide a new method oi" tile eonstrnetion: and such further olu'e ts advantages and capabilities as will later more fully appear.

in the drawings annexed hereto and l oriu- 5 inn a part hereof. Fig. l is a plan view ot a tile eonstrneted neeoriling to our lll\'-i, iion; Fig. 1% is an end view of sueh a tile; Fig". 3 is a perspi-n'tire \'l(\\ shmviug u plurality of adjacent tiles.

Referring more in detail to the drawings numeral l i'lesignates the lower or unpertorated surt'aee ot' the tile '1 while designates the upper or perforated snrt'aee of this tile. 3 are, wehs eonneeting the upper and lower suri'aees which extend beyond the outer wehs 3 to form flanges -l. In the upper surl'aee of the tile are formed suhstaniiall; eireular perforations 5, the lateral edges the upper surface, or upper flanges 41 hein; provided with semi-eireular openings or to form n ith the i'o-operi'iting openings (2 ol the next ailjarent :ilus complete openiuu's similar to .3, in this roiuwetion attention is ,lll(i to the ta t that only one tare of the tile is shown as prorided wth apertures 5 and it is stated that this is by Way of illustratiotn merely as it will sometimes he desirnhle to form these tiles with apertures in both faces. This, therefore. is comprehended within the I scope of our invention.

It is clear that a tile constructed as shown and descrihed will be well adapted for the Serial No 461,410.

passage of heat and air therethrough and to :a material supported thereon, that an extended surtare may he huilt up as shown in Fig). 3 by placing: these tiles edge to edge, and that a tile so constructed Will he suftii-ienlly rein'l'oreed to withstand eousideril llif loads plaeed thereon.

it is of eourse understood that the specific d scription of structure and method set forth ahove may he departed from Without departing from the spirit of our invention as set lorth in this speeifieation and the appended elaiins.

Harin; now lPSX'illlGtl our invention, We elaiin t. (X tile having opposite substantially parallel runes. longitudinally arranged webs ("-i'tendii hriween said faces and leaving their ween longitudinally arranged apertures. Lt least one ol said faces having apertures ntending therethrough into thespaces hetween the wehs and also having}, apertures at edge projecting laterally beyond the outer weli.

L. in a strueture of the eharaeter deserihed, :i plurality of webs. a plurality of lace plate integral with opposite edges 01" snid A'Olfis and exleinling heyond the outer lateral fares ol' both the outermost webs. one of said l'aee plates having therein a pluralii ot' perforations extending: from the outer tare thereof to the spares between the wehs.

3. In a structure of the character described, a plnralitv of webs, a plurality of fin-o plates integral with opposite edges of said wells and extending: beyond the outer lateral 'l'aees of hoth the outermost webs. at least one of said 'l'aee plates having a plurality oi regularl x shaped openings extending therethroluzh to the spaces between the well. the oppositel i pruieeting edges. of said tare plates having therein recesses. ea'h ol' whieh is one half ot one of the apertures extending through the fate plate.

In Witness whereof we hereunto sl'lhserihe our names to this speeitieation.
